Earth's population over the centuries has risen at an increasing rate. So, the correct option is C.

How the population of Earth is increasing?

This sharp increase in population has been primarily caused by an increase in the proportion of individuals reaching breeding age, the gradual extension of human life expectancy, growing urbanization, and quickening migration. This expansion has been accompanied by significant changes in the fertility rate.

One of the key reasons for India's population expansion is a drop in death rates brought on by better medical services and a steady birth rate. The widespread illiteracy in India makes people believe that "children are god's blessings," which makes them opposed to the idea of "family planning." Earth's population over the centuries has risen at an increasing rate.

Therefore, the correct option is C.

2.1explain the body's hormonal response to dehydration​

Answers

Answer:

Vasopressin, a hormon is secreted by pituitary gland which is response to dehydration , causes kidney to excrete less water.

The body's hormonal response to the dehydration is the action of vasopressin in the kidney. The vasopressin decrease the work of the kidney and it leads to decrease the amount of water secreted by the kidney to save water in the body.

What is dehydration?

Dehydration is a condition where there is less water present in the body. There are many reasons of dehydration, like drinking less water or diarrhea. All reactions of the body work by water. So loss of water severely affect the body.

The hormonal response to dehydration is the release of vasopressin by the pituitary gland of the body. The vasopressin saves water from the body to help body fighting with dehydration.  It makes the kidney to filter less water.

Thus, the activation of vasopressin in the kidney causes the body's hormonal reaction to dehydration. Vasopressin lessens the kidney's workload, which causes a reduction in the amount of water the kidney secretes to conserve the body's water supply.

what is menstruation and why does it occurs​

Answers

Answer:

A period happens because of changes in hormones in the frame. Hormones are chemical messengers. The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.

 

It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.

Ca and phosphate reabsorption decreases 5. Ca reabsorption decreases and phosphate reabsorption increases 6. Ca reabsorption increases and phosphate reabsorption decreases

Answers

Answer:

2. Parathyroid hormone level decreases

4. Ca and phosphate reabsorption decreases

Explanation:

When plasma Ca concentration decreases, the action of Parathyroid hormone level decreases  which leads to Calcium and phosphate reabsorption decreases. Parathyroid hormone is responsible for the increase of calcium and phosphorus in the blood when there is low level in the blood so when the re is huge amount of calcium and phosphorus in the blood, the Parathyroid hormone activity decreases which decrease the reabsorption of calcium and phosphorus decreases.

Once the universe was created by the Big Bang, the only abundant elements present were hydrogen (H) and helium (He). ... The conditions inside a star that allow the formation of the higher mass elements can be related to a pushing match between gravity and the energy released by the star.

Voluntourism: An Opportunity Too Good to be TrueA Speech to the Student Body of Evergreen High[1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference.[2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help."[3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved.[4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels).[5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour.[6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed...at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation.What is the counterclaim of this argument? A voluntour experience is a necessary addition to an individual's college resume. The cost of voluntouring is minor in light of what one gets out of the experience. There are better ways to make a difference than mixing tourism with volunteering. Voluntourism is a worthwhile way to make a difference and travel the world.
